To aZZ whom 'it may concern.'

Be it known that I, VOJTCH PUC, a citizen of the Czeeho-Slovak Republic, residing at Prague-'Vinohrady, in Bohemia, have invented certain new and useful Improve ments in Safety Pins. (for which I have filed applications in Austria, filed Oct. l1, 1916, patented Dec. 30, 1918. No. 77,371; in Germany, filed Oct. 7 1916, patented June 15, 1917, No. 298.314; in Spa-in; filed Oct. 4.-, 1916, patented Mar. 15,1920, No. 71,544; in Denmark, tiled Oct. 1, 1916, patented Nov. 26,` 1919, No. 26,530; in` France, filed Dec. 15, 1919, patented June 21, 1920, No. 507 ,413.) of which the following is a specification.

The obj ect of this invention is to construct a safety pin which may be more easily opened and closed than heretofore without hindrance by obstructing edges of the guard.

My improvements are illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of a safetyl pin embodying` my improvements.

Figure 2 shows a section on the line 2 2 of Fig. 1.

Figure 3 is a View on enlarged scale and in perspective of the guard and portions of the pin connected therewith.

The stationary or iixed member A of the pin is connected with the guard B in any suitable way, and the pointed member C is of usual construction. The members A and C are connected by a coil spring at D. The parts A, B and C may be of any usual'construction.

The guard B is, however, of novel construction. In general outline it is .similar to those usually employed. It is formed with a recess having a wide inner portion c and a narrow outer portion c which extends into the edge of the guard, When the pointed portion of the pin is housed in the guard it lies beneath a ange ci of the guard. Then it is desired to open the pin the pointed portion is pressed inward until it comes below the recess c, c when it may be moved outwardly therefrom. As thus far described the guard is of well known form. It is, however, formed with another flange d which, as shown, is curved at its inner edge and lies in the saine plane as the flange d.

The lower side of the guard is formed with a doubly inclined ridge E which is located directly below the recess c, c.

vThe i ridge as indicated at c, the top of the flangel l being` below the upper edge of the ridge, as shown in Fig. 2. The inclined side g of the ridge is below the recess or slot c, c" and this side forms a member of the pin.

By reference to Fig. 2 it will beobserved that the pointed member C issecurely housed when the pin is closed but when it is desired to openthe pin the pointed member ismerely moved inwards in the usual way and it will thenrride up the inclined side g and pass out ofthe guard in the manner indicated by dotted lines. Then the pin is being closed the pointed end is inserted in the slot c, c and when pressed downwards will be guided by the inclination g into its housing in the guard.

A safety pininade in this way is of sim-l ple construction and may be vopened and closed with great facility.

I claim as my invention v 1. A safety pin, comprising a. stationary member` a pointed member, and a guard to guide for the pointed which the stationaryniember is attached, which guard is formed on one side with a slot and on the opposite side with astixed ridge beneath the slot and the' outer end of which is disposed on that side of the slot next the fixed member, said ridge having yan y inclined surface extending to the outer side of the guard for guiding the pointed end of the pin. y

2. A safety pin. comprising a stationary member, a pointed member, and a guard to which the stationary member is attached and which is formed on one side with a slot.

with a slot above theridge and having-a fixed or, stationary Iflange on one side which joins the ridge and is disposed below the top thereof. f i

In testimony whereof, I have hereunto subscribed my name.
